ng command not working [duplicate] - javascript

I am trying to create a project (named ngadmin) via the angular cli but it throws errors on this command: ng new ngadmin. The errors are:
fs: re-evaluating native module sources is not supported. If you are
using the graceful-fs module, please update it to a more recent
version.
You cannot use the new command inside an angular-cli project.
I am not sure what the problem is as this cli was working fine for me a few days ago.

Check in your username folder, if there is package.json and node_module exist. If they are there then delete them.
Notice: you may have created an angular project in your home/username directory. If you delete them it will work.

If using Linux, go to home and delete package.json.

I had this problem as well. Here is how I fixed it:
Go to package.json
Under "Dependencies", find "angular-cli": "^1.0.0-beta.18"
Delete this line ("angular-cli": "^1.0.0-beta.18")
Save file
Hope that helps!

The first warning regarding graceful-fs is due to the fact that angular-cli uses older version of graceful-fs pkg, nothing to worry about that.
The error "You cannot use the new command inside an angular-cli project" signifies you are inside an angular cli project, get out of the angular cli project using cd .. command and try running the command ng new ngadmin it will work.

there is a file package.json
Simply remove it and then Create project.
it will work for sure

Seems like i fixed my problem. I have no idea what happened but i noticed system32 was not in my PATH so i added that and uninstalled and reinstalled the angular-cli package. everything works like a charm now

I had the same issue, the thing was I was not closely following along the tutorial I was watching and I tried using the same directory, I used cd .. to move up in the file structure and it worked like a charm, hope this helps!

i had the same problem today, I started a fresh project and did
npm install -save #angular/cli
and received the error.
I just renamed the package.json to .json2 temporarily and it worked.

Delete the file package.json in current directory where you are trying to create. Then try to install again.

In windows cd/User,Find the package.json,package-lock.json file and delete both the files.
Restart your command prompt and you are ready to go.And try to use this command
npm install --save-dev #angular/cli#latest

You must have used local "npm install #angular/cli" command to install angular locally in your project.
Uninstall local angular using "npm uninstall #angular/cli"
install angular globally using "npm install -g #angular/cli"
and then try "ng new ngadmin"
Because "ng new projectName" will automatically install angular/cli locally as a dev-dependency

npx create-nuxt-app <project-name> not working

I want to create Nuxt.Js app using npx. But i am getting following error.
You have a space in your Windows username. This is a problem with NPX.
This is the path that NPM sees (which is right)
This is the path that NPX sees (which is wrong)
You can fix it by changing your NPM-Cache to another directory (without a space in the path):
npm config set cache C:\your\new\path\npm-cache --global
Source:
https://github.com/zkat/npx/issues/146#issuecomment-384016791
I changed npm-cache directory by writing following command
npm config set cache C:\tmp\nodejs\npm-cache --global
After that npx create-nuxt-app <project-name> worked perfectly.
I had it working using this command.
npm init nuxt-app <project-name>
This problem was resolved in a reddit
https://www.reddit.com/r/vuejs/comments/ie8vab/createnuxtapp_not_working_anyone_else_had_this/
Install it with:
npm i -g create-nuxt-app
Usually npm/npx should propose you to install, but it might not work
This issue can appear if during first try the installation was aborted
I have encountered similar problem and I have multiple spaces in the username.
If the above solutions does not work for you on Windows, there is another way.
Run VS code editor as an administrator.
Open the integrated terminal by clicking on Terminal > New Terminal or by pressing CTRL + SHIFT + '
Instead of using npx use the following
npm init nuxt-app project-name
Point number 3 will only work if you run the VS code editor as Administrator.
I am sure it is the same with external terminals. Run CMD/Gitbash as Administrator
Hope this helps. :D

The react-scripts package provided by Create React App requires a dependency:

There might be a problem with the project dependency tree.
It is likely not a bug in Create React App, but something you need to fix locally.
The react-scripts package provided by Create React App requires a dependency:
"babel-eslint": "9.0.0"
Don't try to install it manually: your package manager does it automatically.
However, a different version of babel-eslint was detected higher up in the tree:
create .env file in your project file and add the following statement
SKIP_PREFLIGHT_CHECK=true
Save the file
Remove node_modules, yarn.lock, package.lock
Then reinstall node_modules with
npm install
This should work
I had the same problem and do all the suggested steps but the problem still, so, my error is that i have a reactApp inside other Javascript App i had this structure.
--MyProjects
----NodeJsApp
----node_modules of NodeJsApp
----package.json of NodeJsApp
----ReactApp
------node_modules of ReactApp
------package.json of ReactApp
The problem solved to me deleting my ReactApp node_modules directory, then i do a reestructure of my directories because i have a disaster.
--MyProjects
----NewDirectory (inside all about NodeJsApp)
------node_modules of NodeJsApp
------package.json of NodeJsApp
----ReactApp
------package.json of ReactApp
After that i do :
npm install
and then npm start and my problem has fixed, i think that the problem is that the parent directory cant have a javascript /nodeJs/ project or something that have node_modules .
Part of the output you provided says:
Check if C:\Users\chawki\node_modules\babel-eslint is outside your project directory. For example, you might have accidentally installed something in your home folder.
Browse to C:\Users\chawki\node_modules\ and delete the babel-eslint folder, or simply delete C:\Users\chawki\node_modules.
I just deleted the node_modules folder (for me it was C:\user\[yourUserName]\node_modules\) and re-installed it.
Here What i did...
C:\user\[yourUserName]\node_modules\babel-eslint and delete the file
C:\user\[yourUserName]\node_modules\eslint and delete the file
Delete your eslint and babel-eslint file from your node modules on your computer e.g. -C:\Users\vishnu\node_modules -delete eslint and babel-eslint file.
In your project:
yarn remove eslint
yarn add --dev eslint#6.1.0
yarn remove babel-eslint
yarn add --dev babel-eslint#10.0.3
If you dont want to create .env file there is another alternative you can pass the SKIP_PREFLIGHT_CHECK=true directly in the script.
For Example
"start": "SKIP_PREFLIGHT_CHECK=true react-scripts start",
in package.json
resolutions:{
"babel-eslint": "9.0.0"
}
if you reinstall your all dependencies, you will be forcing "babel-eslint" to be version "9.0.0". if you start your app, you will have no issue.
My problem was I installed webpack as a global package... after i deleted webpact and run npm install, the problem was gone
Make sure you don't have a global webpack package or somewhere higher up the directory structure.
In my case, I had it globally installed. Deleting and then running npm install and then npm start worked perfectly.
Run npm ls babel-eslint and see which dependencies are using it or installing another version. Try updating those libraries.
It worked for me.

ENOLOCAL: can't find package.json file after publishing npm package

Ecosystem
using npm#6.1.0
using node#v8.11.1
Context
I have a JS project that includes a local dependencie :
package.json :
"dependencies": {
"my_local_module": "file:my_local_module"
},
Then, I published the project as npm private package : so far everything is OK.
Issue
When I try to install my private package, I have this issue :
33 error code ENOLOCAL
34 error Could not install from "node_modules\#my_scope\my_project\my_local_module" as it does not contain a package.json file.
Of course, the package.json file exists. When I try to copy manually the project from gitHub instead of installing it with npm, it works perfectly fine but I really would like to make it works with :
npm install #my_scope\my_project
Is there a specific way to publish packages when they include local dependencies or anything like that ? Thank you for your help.
You can try to delete your package-lock.json file
I had the same problem and error. The package-lock.json was still doing a reference to "file:my_local_module".
I deleted it and re npm installed the module to make it work
I found a report of a similar issue within the npm cli github
https://github.com/npm/cli/issues/1756
It appears this may be an issue with npm v6 (I was using version 6.14.12). Updating npm to v7 seems to have solved this issue for me.

running lines in my node.js command prompt

I am new to node.js and Github. I was trying to save some work by using command git add -A and the then I saw these lines below and some many of the lines are just running non-stop. I typed ctrl+c to stop it, but anyone knows what are just happened or what did I do wrong??
Thanks
This is because of how git treats the space character.

Thanks #bcorbella for the answer. Just a small precision to be sure you won't do this as a beginner but never add the node_modules into your git project. Create a .gitignore file with at least:
node_modules
Use npm init, npm install <module> --save to create a package.json... then do simply a npm install when you are checking your project.
More info in here https://docs.npmjs.com/getting-started/using-a-package.json
try setting the config core.eol to native and see if you will get the same error, i see no reason why you should be tracking the node_modules/ folder.
> git config --global core.eol native

Using specific version of npm shrinkwrap

I am deploying my node.js app to Appfog but since their install script cannot parse npm-shrinkwrap.json the whole deploy process fails.
An example dependency in shrinkwrap.json today looks like this
"async": {
"version": "0.2.10",
"from": "async#0.2.10", <--- This line breaks install script at appfog
"resolved": "https://registry.npmjs.org/async/-/async-0.2.10.tgz"
},
I went through the whole shrinkwrap file and removed the "from" part from each dependency declaration and i managed to upload my application, and it works.
So my question is , how do i use an older version of npm shrinkwrap so i can get the version of shrinkwrap.json that i need?
Appfog support told me i need to use version 1.1.21 but i have not succeeded in installing it.
Please ask if some info is missing.
if you just want to use an older version of npm, you can install it via npm (i know that sounds strange, but its possible)
npm install npm#1.1.21
edit: so you try to install a version of npm which does not exist. just run
npm view npm
and take a look at the property version, to see which versions you could install via npm.
you will see that 1.1.21 does not exist in the registry, which means that you should try to install it via github (see answer by #sakai).
but then you see the next problem. you are using node#0.10.26, and npm 1.1.21 is probably not compatible with node#0.10.x.
so i for myself see basically 2 possible solutions:
Solution 1:
use n (or maybe nvm for switching node-versions back and forth. you could try to install a node#0.8.x version and try to install npm#1.1.21 there, and when done with shrinkwrapping switch back to your current node version.
Solution 2
you could setup some kind of grunt/gulp-task (i hope you use one of them) to run grunt/gulp shrinkwrap, which generates your shrinkwrap.json (via npm shrinkwrap) and when done cleans up your shrinkwrap.json
Try this:
npm install https://github.com/npm/npm/archive/v1.1.21.tar.gz
node ./node_modules/npm/bin/npm-cli.js shrinkwrap
Another—possibly simpler—solution is to just include node_modules into your repo.
